HOME > Bolt seals > EnaBolt 4


Although it is the most cost-effective barrier seal in the range, the EnaBolt 4 easily fulfils the role of a barrier seal with a pull strength of over 500kg while requiring a bolt cutter to remove. The attached pin design keeps the pair of matching numbers on the pin and barrel together until application.
